Dodgem

ABSTRACT

This creation is in respect of the dodgem, particularly means a kind of dodgem played by child, could be contractible for packing, easy for assembly and convenient in operation. The dodgem consists of the body, seat on the body, and rear wheels at rear below of the body, a steering axle frame at upper front of the body and a front wheel mounting at front below of the body. Front wheels at two sides of the front wheel mounting, and a steering axle extended up from the front wheel mounting through the body and the steering axle frame set on body, then is fixed on the steering wheel for child&#39;s holding and operation. And because the structure between body and the steering axle frame is separable that the user could assemble and separate them by self to reach the advantage of reducing the volume and being stored easily.

BACKGROUND OF THE INVENTION

[0001] As the likely dodgem for child's play now in market, there is abearing 12 as shown on FIG. (1) on the bearing block 11 of body 1 tokeep turning between body 1 and steering axle 10. And after the steeringaxle 10 passing through the central hole 120 of bearing 12, then fastenswith front wheel frame 1 to provide the turning for steering axle 10 bybearing 12. However, to set bearing 12, in addition to more costs ofbearing 12 resulting in increment of overall cost of dodgem, the bearingblock 11 of body 1 is required to matching the height of bearing thatcauses to increase the height of body accordingly. As a result, thetotal height of body of dodgem is over leading to raise the point ofgravity that the body is easy overturning to create danger whileplaying, but could not produce the interesting for player.

[0002] Next, the body for finished dodgem sold in market presently ismade of one-unit forming. To show double colors on body during theprocess manufacturing the dodgem, it's required to changing the color bythe way of coating that further increase the overall packing cost ofdodgem and the cost of transportation.

[0003] In consideration of the fact, the inventor researches the shortof dodgem sold in market now to create this product.

SUMMARY OF THE INVENTION

[0004] One of characteristics of this creation is to place two pieces ofsliding washer inside the sliding washer flute of front wheel mountingfor steering axle's passing through in stead of bearing that not onlycan produce better smoothness in turning, but also reduce the volume ofstructure effectively while the steering axle is turning.

[0005] Another characteristic of this creation is a steering axle frameset in the front of body, which can form a double-color system withbody, and can be disassembled and assembled at one's will to reduce thevolume of packing and storage for dodgem.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0016] The practical example (1) of dodgem for this creation, as shownon FIGS. 3 to 5 that this creation consists of body 2 and on which aseat 20. The seat 20 with the outlook could open toward one side to froma stuff space 21. And below the seat 20, there are rear wheels 23 set onbody 2. Both rear wheels 23 move directionally to match the operation offront wheels. In front 22 of the body 2, there are two combined holes220 set for insert of combined plug 30 of steering axle frame 3. And usethe one-unit forming elastic buckle 31 below the combined plug 30 toinsert in the down wall 222 of combined holes 220 (as shown on FIG. 4).There is steering axle hole 32 on steering axle frame 3 and steeringaxle hole for body 221 on body 2 set for steering axle's passingthrough.

[0017] Next there are front wheels 5 in front below the body. The frontwheels 5 are set on the front wheel mounting 50 (as shown on FIGS. 4 to6). The front wheel mounting 50 has a sliding washer flute 51 for insertof two pieces of washer 52 (or plural washers), and the fixed hole ofsteering axle 53 has bottom wall 530 with screw hole 531 as well as thedeeper outer surround 532. The steering axle 4 could insert into thefixed hole of steering axle 53, and the screw 54 is, from below of thescrew hole 531 upward fastened on the nut 40 located inside the steeringaxle so as to combine the steering axle 4 with front wheel mounting 50.

[0018] And after the steering axle 4 extends up and through the steeringaxle hole 32 of steering axle frame 3, then fastens with steering wheel6. The way to fasten steering wheel 6 with steering axle 4 is same asthe way to fasten front wheel mounting with steering axle. Afterfastening, the structure of this creation is very firm not easy todisengage so as to meet the safe norm.

[0019] As for the FIGS. 7 and 8 show the practical examples 2 and 3.Among the figures, both practical examples are derived from practicalexample 1. The practical example 2 is to produce steering axle frame 3Awith body as one unit. However, the way of combining the steering axle 4with front wheel mounting 50 is same as the practical example (2) thatboth are made by two pieces of washer 52 (as shown on FIG. 6). And thefront of practical example 3 is derived from practical example 1 thatcombines the steering axle frame 3 with two combined holes 220 of thefront 22 of body. As for the way of combining the Steering axle withfront wheel mounting 50 could use Bearing 7 in stead of two pieces ofwasher that has the function to reduce the height of body too and couldsmooth the turning of steering wheel.

What is claimed is:
 1. The dodgem consists of body, seat at the rearside of body, and rear wheels set at rear below of body; and there aretwo combined holes and steering axle hole that the two combined holes onupper front of body are used for inserting two sides of steering axleframe. The elastic buckle at two sides of steering axle frame is set tobite the wall below the combined holes. As for the steering axle holesof steering axle frame are used for Steering axle's passing through;Next, there are front wheels set at front below the body. The frontwheels are set at two sides of front wheel mounting. And there is asliding washer flute inside the front wheel mounting, which is set fortwo pieces of sliding washer. In addition, there are fixed holes ofsteering axle used for insert of steering axle. And the screw is fromthe screw hole upward inserted into the nut inside the steering axle.And after the steering axle extends upward and passes through thesteering axle holes at steering axle frame, then fastens with steeringwheel.
 2. According to the item 1 of scope of application for patentregarding the structure of dodgem that the steering axle holes canproduce with body as a one-unit forming. However the sliding washerflute is set in front wheel mounting, and on which two pieces of washerare set for steering axle's passing through.
 3. According to the item 1of scope of application for patent regarding the structure of dodgem,among which there is combined hole in front of body set for fasteningthe steering axle. And the front wheel mounting is set in front below ofthe body. And the sliding washer flute is set on front wheel mounting,which could be set for bearing and for steering axle's passing through.
